Hash Type Finder
Identify which algorithm likely produced a hash.
If you're handed a hash with no context, its length and format usually reveal the algorithm family.
About Hash Type Finder
Paste a hash to see which algorithms could have produced it, based on its length, character set, and prefix — for example 32 hex characters suggests MD5, and a string starting with $2b$ is bcrypt. Useful when you inherit a database dump or config file and need to know what you are looking at.
If you're handed a hash with no context, its length and format usually reveal the algorithm family. The hash type finder inspects the value — hexadecimal length, character set and well-known prefixes such as $2b$ for bcrypt — and lists the algorithms it could be, so you know how to handle it.
How to use Hash Type Finder
- Paste the hash into the input field.
- Read the reported length in characters.
- See the list of likely algorithms.
- Use that information to choose the right verification method.
Key features
- Recognises MD5-length, SHA-1, SHA-2 and other common hex hashes.
- Detects prefixed formats such as bcrypt and Argon2.
- Explains when several algorithms share a length.
- Runs locally in your browser.
Common use cases
- Identifying the algorithm used in an exported user table or config file.
- Auditing a system to find weak hashing such as MD5 for passwords.
- Working out which tool to use to verify a checksum.
